FYI, following is a press release from the Turkish Embassy in Washington DC. I found it at www.turkey.org. It is not copyrighted, please feel free to redistribute. Personally, I feel strongly that Birgenair should sue the German Goverment for the premature early negative press exposure. AMC ---------------------------------------- GERMANY BASED TURKISH "BIRGENAIR" CLEARED OF ACCUSATIONS Washington, D.C., June 20, 1996 -- The U.S. National Transportation Safety Board has determined that the crash of Birgenair 757-200 after takeoff from the International Airport in Puerto Plata, Dominican Republic on February 6, 1996, killing all 189 passengers and flightcrew, was the result of a mechanical deficiency. The Safety Board's findings run counter to the hasty conjectures first alleging that the inexperience of the Turkish airline's pilots contributed to the tragic accident. Information recovered from the cockpit voice recorder (CVR) and flight data recorder indicates that the pitot static system aboard the accident flight, which is responsible for calculating airspeed, transmitted an erroneous airspeed indication. It is evident that the discrepancy in airspeed led to much of the confusion in the cockpit that preceded the accident. Initially, hasty accusation claimed that had the captain activated his alternative data source during the accident flight, it would have removed the erroneous airspeed indication and prevented the subsequent stalling of the aircraft. The Safety Board, however, found that Boeing Commercial Airplane Group's Operations Manual for B757 did not contain procedures either to identify an erroneous airspeed indication or to select the alternate air data source as a corrective maneuver. Moreover, the Boeing 757 EICAS system that provides alert messages to advise the pilots of system failures and non-normal operational conditions does not produce a message to alert pilots regarding an unreliable airspeed indication. The Safety Board recommended that the Federal Aviation Agency stipulate that Boeing revise its B757 flight manuals to alert pilots to the conditions that forewarn an erroneous airspeed indication, and include a detailed emergency procedure addressing the identification and elimination of an erroneous airspeed indication. In addition, Boeing should modify the crew alerting systems of the B757 to activate a "caution" alert when erroneous airspeed is detected. Already, such measures have been adopted by American Airlines and Delta Airlines. It is expected that as the principal commercial airlines manufacturer, Boeing will incorporate any and all safety precautions, no matter the cost, so as to avoid future tragedies.
